It is generally accepted that mammalian skeletal muscle excitation-contraction coupling occurs through a mechanical interaction between the L-type voltage sensitive Ca2+ channel of the sarcolemma – dihydropyridine receptor (DHPR) – and the Ca2+ release channel of the sarcoplasmic reticulum (SR) – ryanodine receptor type 1 (RyR1) – as opposed to an inward Ca2+ current through the DHPR
